In fact, the placement of wireless LAN access points in Starbucks coffee houses turns those locations into Web portals, as they provide customers with the ability to wirelessly access the Internet. A wireless portal can be considered to represent a location that supports wireless LAN access and provides a network connection to another network, with the other network most commonly being the Internet. Although most portals are constructed for the use of travelers, a new type of portal was beginning to receive a significant degree of interest when this book was written.
This is because a cosine carrier wave is either added or subtracted from a sine wave to produce the required phase shift in the form of a modulated sine and cosine wave.

A sine wave represents an oscillating wave that varies in height from zero to a maximum value and back to zero for one half of its cycle. Then the wave becomes negative for the second half of the cycle, ranging in value from zero to a minimum value and back to zero. Returning to Exhibit 1, note that the top portion illustrates a sine wave operating at exactly one cycle per second. Thus, over a two-second interval it would have two cycles, over a three-second interval it would have three cycles, etc.
